Appearance fees
The appearance fees vary from skater to skater and are based on their contracts (either for the season or by the event) with the USFS. I seem to recall a number of around $300,000 tossed around a couple of years ago wrt Todd Eldredge and Alexei Yagudin (this was for three events, iirc, so it would be $100,000/event). Of course, my memory could be totally wrong and it was $100,000 for all three events, but I'm thinking it was the higher number, because I thought -- WOW, that quite a bit of money. (It might have been that the contract also included some other appearance fees or obligations, too.) Anyway, I'm not sure if having the prize money will have any affect on the appearance fees, but I do know that these events all offered them. Offering prize money would be an added incentive to skate well -- but I never really thought any of the skaters "phoned in" their performances. None of them want to skate badly -- or appear on TV in an embarrassing competition.
